| 摘 要： | 结合实例,对复杂多体系统动力学建模的基本方法进行了研究,建立了一种机车整车虚拟动力学模型。结合机车动力学建模系统中的体之间的铰接、约束和力元等建模技术的难点,说明如何正确进行复杂机车多体系统的动力学建模。实例中对机车动力学模型输入标准轨道谱,分析其在标准轨道谱的随机激励下车体结构的响应特征,并对动力学平稳性结果进行部分评价。

| Abstract: | In combination with instances,the paper studies the method for the dynamic modeling of a complex mult-body system,creating the virtual dynamic model of a locomotive.By using some difficulties in a locomotive′s dynamic modeling such as joint connection,constraint treatment and force element,the paper explained how to do its complex multi-body system dynamic modeling.It analyzed the characteristics of the locomotive-body′s structure response by stochastic excitation with input data of standard railway stochastic spectrum and partially evaluated its dynamic smoothness results. |
